Conciseness

Dense and operational throughout — no explanations of concepts Claude already knows — with only minor redundancy: the 回传处理 table and the "若 attempts > 1，附上 iteration-patches/attempt-${attempts}.md 摘要" line are duplicated between §2 and §3.

Actionability

Exact file paths (${WORKDIR}/req.md, questions.md, spec.md), status codes (ok / blocked_on_questions / fail / spec_insufficient), round limits (3 / 5), template section anchors (§2.0, §2.1, §3, §1.2) and snapshot naming (spec.md.prev-attempt${N}-round${R}) make it executable; formats for last_failure and history records are left unspecified.

Workflow Clarity

Five clearly sequenced stages with an exhaustive re-entry decision table (§1), an explicit quality-validation checklist with pass criteria and failure routing (§4), and complete feedback loops — blocked→answer resume, fail→回退重入 outside the attempt, and round-limit escalation per §1.2.

Progressive Disclosure

The orchestration overview correctly keeps the 287-line clarification guide and 134-line template in references/ (both exist and match their cited roles), and references are one level deep with stated purposes; however `state-mutation-guide.md` is cited without a path prefix and most referenced templates live in the parent bundle, unverifiable from this skill's directory.

Specificity

Names several concrete actions — "技术澄清段审查需求并产出澄清结论", "specify 段生成 spec.md", "以 blocked_on_questions 退出…以 answer 指令重入继续" — but coverage of the stage's full behavior (validation, state update, rollback) is incomplete.

Completeness

The "what" is clear — a two-stage technical clarification and spec-generation pipeline stage sharing a questions.md proxy-question loop — but there is no "Use when..." or equivalent trigger guidance; when to invoke it is only weakly implied by "迭代执行流水线…阶段".

Trigger Term Quality

Relevant domain keywords appear (技术澄清, 规范生成, spec.md), but there are no synonyms or variations (技术评审, spec 撰写, 技术把关) and much of the text is internal mechanism jargon (blocked_on_questions, 代问循环) rather than phrases a caller would naturally say.

Distinctiveness Conflict Risk

The niche is distinct — a specific pipeline stage with unique questions.md proxy-loop mechanics — but without explicit trigger boundaries it has minor overlap risk with sibling requirement-clarification or spec-generation sub-skills.
